United States National Herbarium (US-Botany)

The United States National Herbarium was founded in 1848, when the first collections were accessioned from the United States Exploring Expedition (50,000 specimens of 10,000 species). Current holdings total 5 million specimens, making this collection among the ten largest in the world representing about 8% of the plant collection resources of the United States. The herbarium is especially rich in type specimens (@110,000).
